During practicum on Friday:
Correlation tractography
Nonparametric tests
Hands-on: white matter tract correlated with BMI
- Download cmu60.db.fib.gz and cmu60.csv.
- Set permutation count to 500.
- uncheck [FDR control] and run analysis using different T threshold (2 and 3).
- check [FDR control] (< 0.05) and run analysis use different T threshold (2 and 3)to see how it affects results.
Hands-on: group stratified analysis
- Download cmu60.db.fib.gz and cmu60.csv.
- Repeat 1 on male group.
- Repeat 2 on female group.
Hands-on: post-hoc analysis
- Use tractography results from task 1 to extract QA values from the connectometry DB file.
- Plot scatter plot (BMI vs QA).
